    If you dont know how to find the area of a circle, then you need to review your course material.

    Do you remember the formula? You answered, No Not: I did, not, here it is, nothing. just No. So, how do we calculate the area of a circle? post your thoughts, and then we can proceed.

    this isnt math, its just a formula. formulas are memory stuff, not math perse. and there is something off in your option, that i agree.

    half of 4 yes. so pi 22 assuming your paste ate the exponent marker. and now, this is why you finding the formula was important, I was considering using 2 pi r instead - which was wrong in my head.

    so the answer is 3.14 * 2 square

    Jamie has a deck of 60 sports cards, of which some are baseball cards and some are football cards. Jamie pulls out a card randomly from the deck, records its type, and replaces it in the deck. Jamie has already recorded six baseball cards and nine football cards. Based on these data, what is, most likely, the number of baseball cards in the deck? 12 15 24 30

    a ratio is the number of items in one set, compared to the number of items in a different set. say I have 3 apples and 2 oranges, the current ratio of apple to oranges is: 3:2

    15 is required 6 of one, 9 of the other, and 15 total 6 :9 :15 now the ratio stays consistent for any multiple, say k 6k :9k :15k we want the value of 6k we know that 15k = 60, since we have a total of 60 cards in the entire deck what should the value of k be?
